General NFS exports question

[zyberwoof]

I'd like to make an export rw for one machine, and ro for the rest. I'd like to do something like this:

/dir 192.168.1.0/24(rw)
/dir/dir2/dir3 192.168.1.5(rw) 192.168.1.0/24(ro)

Essentially, I'd like to be able to make dir3 writable from only one machine on my local network, and read only from the rest. What is the correct syntax for this?

I'd have the machine hostnames resolved in order and use
/build buildhost0[0-9].local.domain(rw)
/build buildhost1[0-9].local.domain(ro)

Or you can check the export manpage for details.

There is an issue with the /dir export allowing everything too. Mixing rw and ro on the same storage exports is a bad idea, IMHO.
